Definitions
- the deposition of metals by electrolysis from solutions is normally carried out in masonry cells, coated with insulating materials, resistant to acids or alkalis and to temperature, in which the electrolyte is normally fed by one end of the cell, while The spent electrolyte is discharged from the opposite lower end, if the supply has been from the upper edge or vice versa.
- the transverse circulation of the electrolyte has been used, that is to say parallel to the faces of anodes and cathodes, by means of the introduction of perforated pipes, in which the feeding is carried out by means of a perforated longitudinal pipe, located at the bottom next to the cell, while the discharge is carried out by overflow, or through another perforated pipe, located on the opposite upper side of the cell.
- air is usually injected to stir the electrolyte and to uniform the concentration of the latter, which helps to avoid the crystallization of the electrolyte and diminish the effect of the boundary layer.
- This is done by introducing perforated tubes through which air or neutral gases are injected, which requires Ia provision of fans, air supply ducts and perforated distribution pipes.
- removable insulating structures are used, as indicated in the Chilean patent application No. 0 1020-04, in which they are mounted anodes, cathodes, electrolyte circulation pipes and air distribution pipes, all of which can be removed from the cell at the end of the production cycle, for maintenance, drastically reducing production losses for that reason.
- Figure 1 shows a perspective view of the supporting structure of insulating material, which can be introduced and removed from the cell, in which the vertical and horizontal guides in which the anodes and cathodes are mounted, and They fix the pipe circuits for the distribution of the electrolyte and of the electrical conductors for the generation of the agitation gases of the electrolyte.
- Figure 2 shows a perspective view of the support structure of insulating material, in which the set of electrical conductors mounted in the structure is appreciated.
- Figure 3 shows a perspective view of the electrical conductors, mounted on the lower crosspieces of the support structure of insulating material.
- Figure 4 shows a perspective view of the electricity supply conductor, connected to three circuits of electric conductors, producers of bubbling gas.
- Figure 4A shows a perspective view of the electricity supply conductor, connected to three circuits of electric conductors, producers of bubbling gas, in which the supports for mounting and fixing to the supporting structure of insulating material are shown.
- Figure 4B shows a perspective view of the electricity supply conductor, connected to three circuits of electric conductors, producers of bubbling gas, in which isolated and non-isolated sectors of said conductors are shown.
- Figure 5 shows a perspective view of the electricity supply conductor, connected to two circuits of electric conductors, producers of bubbling gas.
- Figure 6 shows a perspective view of the electricity supply conductor, connected to a circuit of electric conductors, producing bubbling gas.
- Figure 7 shows a perspective view of the electricity supply conductor for the circuits of the bubbling gas producing electrical conductors.
- the present invention consists in the fixation of one or more electricity supply circuits to one or more circuits of electrical conductors without insulation, or with located isolation sections, which are located in the lower zone of the electrolytic production cell, or at a support structure of anodes and cathodes of insulating material, independent of the production cell, which can be removed and installed in it, with or without the anodes and cathodes already placed in the guides of the support structure.
- a circuit of insulated power supply conductors (8) has been fixed, on the outside and next to a support structure of anodes and cathodes, constructed in electrically insulating material, in which a plurality of anodes and cathodes are located, while below the lower frame (7) of the support structure, one or more circuits of electrical conductors have been fixed by means of supports (15) without insulation, or with localized insulation sections (16), which are connected to the power supply (8), through connectors (12, 13 and 14) to uninsulated conductor circuits or with localized insulation sections (9 , 10 and 11).
- the isolated electricity supply conductor (s) are fixed to the vertical walls of the cell, while the electrical circuit (s) without insulation, or with sections of localized insulation, they are fixed directly to the floor of the cell.
- the non-insulated electrical conductor circuit (s), or with localized insulation sections, can be constructed of either solid single-wire or multifilar wire, of metal coated with a mixture of metal oxides. (Known in English as MMO, short for "Mixed metal oxide”).
- the control of the amount of bubbles can be done by modifying the voltage or current applied between cathodes and the circuits (9, 10 and 11) of conductors without insulation or with localized insulation sections (16).
- a support structure of insulating material constructed of fiberglass reinforced plastic, with anode guides and cathodes of insulating material, loaded with 61 insoluble anodes 1200 millimeters high by 800 millimeters wide, with ears supporting Ia conductive bar, and 60 stainless steel cathodes 1140 millimeters high and 880 millimeters wide, spaced at 95 millimeters between centers.
- the pipe is connected for the circulation of electrolyte to the connection (1), and the electrical energy is connected to start the production operation.
- the electrical conductors without insulation or with the conductor with localized insulation sections are made of titanium coated with a mixture of metal oxides of 3 millimeters in diameter.
- the electrolyte is circulated at a flow of between 10 and 30 cubic meters per hour and the electrical energy is fed at a potential of 1, 7 to 2 volts between the circuits of uninsulated conductors or with conductors with located insulation sections (9 , 10 and 11) with respect to the potential of the cathodes. This potential difference produces the release of oxygen in the surface of the conductors without insulation or in the localized insulation conductors (16).
- the electrolyte is stirred, improving the uniformity of its concentration, decreasing the boundary layer and thereby improving the quality and current efficiency of the deposition of the metal.
- the maintenance time is reduced, in relation to the maintenance of the fans and air supply and distribution pipes.
- the chemical and physical quality of the cathodes is improved, their dimensional uniformity and therefore, the dispersion of their weight decreases and the energy efficiency is improved.
